NEW DATA ON DYTISCIDAE, HYDROPHILIDAE, HYDRAENIDAE, DRYOPIDAE AND HETEROCERIDAE (COLEOPTERA) OF NORTH OSSETIA

The species Ochthebius anatolicus Janssens, 1963 (Hydraenidae) is recorded in Russia for the first time. A new record of Laccobius hindukuschi Chiesa, 1966 (Hydrophilidae) confirms the presence of the species in the fauna of Russia and is the first for North Caucasus and the Republic of North Ossetia. Six species are recorded from North Ossetia for the first time: Agabus dilatatus (Brullé, 1832) (Dytiscidae), Laccobius alternus Motschulsky, 1855, Cercyon lateralis (Marsham, 1802) (Hydrophilidae), Ochthebius anatolicus (Hydraenidae), Praehelichus asiaticus (Motschulsky, 1845) and Pomatinus substriatus (P.W.J. Müller, 1806) (Dryopidae). The records of Hydroporus transgrediens Gschwendtner, 1923 (Dytiscidae) and two species of Heteroceridae (Augyles maritimus (Guérin-Méneville, 1844) and Heterocerus fenestratus (Thunberg, 1784)) are confirmed by new examined material. Laccobius alternus is additionally recorded from Kabardino-Balkaria Republic for the first time. Original photographs of the habitus, male genitalia and macrohabitats are provided for some species; such photographs for Agabus dilatatus have never been published before.
